Abstract

A new garden rose plant of the compact floribunda class which has abundant, light pink and apricot flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Botanical classification: Rosa hybrida.

Variety denomination: ‘POULac013’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female seed parent, an un-named seedling, and the male parent, an un-named seedling. The two parents were crossed during the summer of 1994 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULac013’.

The new variety may be distinguished from its female seed parent by the following characteristics:

The seed parent has a tall growth habit, and has salmon pink flowers. ‘POULac013’ is compact and has light pink and apricot blend flower color.

The new variety may be distinguished from its male pollen parent by the following combination of characteristics:

The pollen parent has pink flowers while ‘POULac013’ has light pink and apricot blend flower color. Additionally, the pollen parent has more flower petals than ‘POULac013’.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

- 1. Uniform and abundant light pink and apricot colored flowers;
- 2. Vigorous, but compact and even growth when propagated both as a budded rose and on its own roots;
- 3. Disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULac013’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1994-1995 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULac013’ was selected in the spring 1995 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULac013’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1995. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULac013’ are true to type and are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems, of ‘POULac013’. Specifically illustrated in the first drawing;

FIG. 1.2; Sepals, receptacle, and peduncle;

FIG. 1.3; Flower buds at various stages of development;

FIG. 1.4; Flower petals, detached;

Specifically illustrated in the second drawing;

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULac013’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants were budded on to Rosa multiflora rootstock, and are 3 years of age. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘POULrek’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 9,688 issued Nov. 12, 1996, are compared to ‘POULac013’ in Chart 1.
